Hi,
I've been using SA a long time. Lately, I'm getting more and more
spam with emoticons in the subject line. I'd say about 90% of my
emails with emoticons in the subject are spam. I'd like to create a
local rule which scores email with emoticons in the subject. I saw a
previous discussion on this in the archive, but it was focused on
whether such emails were /always /spam. I think an emoticon rule, in
combination with other rules, will help my installation. I've tried
to match as follows, but it won't lint. I'm not really a perl
programmer. I've written several other more conventional local rules,
but here I'm a bit out of my depth. I'd appreciate some guidance.
# Local Rule for Emoticons in subject
subject EMOTICON_IN_SUBJECT Subject =~ /\p{Emoticons}/
score EMOTICON_IN_SUBJECT 3.0
describe EMOTICON_IN_SUBJECT Subject Line Has Emoticons
-CJ
The following regex will detect a good amount of Emojis:
|/[\u{1f300}-\u{1f5ff}\u{1f900}-\u{1f9ff}\u{1f600}-\u{1f64f}\u{1f680}-\u{1f6ff}\u{2600}-\u{26ff}\u{2700}-\u{27bf}\u{1f1e6}-\u{1f1ff}\u{1f191}-\u{1f251}\u{1f004}\u{1f0cf}\u{1f170}-\u{1f171}\u{1f17e}-\u{1f17f}\u{1f18e}\u{3030}\u{2b50}\u{2b55}\u{2934}-\u{2935}\u{2b05}-\u{2b07}\u{2b1b}-\u{2b1c}\u{3297}\u{3299}\u{303d}\u{00a9}\u{00ae}\u{2122}\u{23f3}\u{24c2}\u{23e9}-\u{23ef}\u{25b6}\u{23f8}-\u{23fa}]/ug

But it is not the greatest thing if you want to get a count out of that.

However, I may have a solution for you with the CHAOS plugin:
https://github.com/telecom2k3/CHAOS
You can get (but shouldn't) Emojis even in From names, like this actual one:
DHL☺com
CHAOS will also help you with Unicode Character spoofs, via its
UniBabble rulesets:
ᴀмαzσи ᴘ𝔯𝔦𝔪ё
𝘼𝔪𝔞𝘻𝙤𝘯 𝘾𝘶𝘴𝙩𝙤𝘮𝘦𝘳 𝙎𝔢𝘳𝙫𝘪𝘤𝔢
Amαzoɴ Priⅿë
🅰🅼🅰🆉🅾🅽 🆂🅴🆁🆅🅸🅲🅴
𝐀𝐦𝐚𝐳𝐨𝐧 𝐍𝐨𝐭𝐢𝐜𝐞
...
...
CHAOS will run on PERL 5.18 and later.
